GitHub said on April 7, 2026 that Copilot CLI can now use a developer’s own model provider or fully local models. The change adds Azure OpenAI, Anthropic, offline mode, and optional GitHub auth while keeping the same agentic terminal workflow.
GitHub Changelog's April 7, 2026 X post said Copilot CLI can now connect to Azure OpenAI, Anthropic, and other OpenAI-compatible endpoints, or run fully local models instead of GitHub-hosted routing. GitHub's changelog adds that offline mode disables telemetry, unauthenticated use is possible with provider credentials alone, and built-in sub-agents inherit the chosen provider.
